Verify Power and Muting Options

Check the control pod for the speaker system and verify the power LED (Figure 1-1) is lit green:
  1. If the LED is not lit at all, unplug the power connection from the control pod to the back of the bass module and reseat the connection.
  2. If it remains unlit, plug your power cord into a different wall outlet.
  3. Verify that the power switch on the back of the bass module is set to ON (Figure 2).
  4. If the LED is lit amber, your speaker system is muted. This can occur if you have manually muted the system or plugged headphones into your control pod:

    • If you have headphones connected (Figure 1-3), disconnect them from the control pod.
